The Sydney Sprint Orienteering race starting opposite Middle Head Oval in Mosman is part of a series of short course sprints (2.5km to 4km) with lots of controls and lots of changes of direction, and held mainly in urban environments (uni campuses, former hospital sites, sporting complexes etc).
"Sprint" is the newest format in orienteering. Think of it as the T20 of orienteering. At the elite level it is meant to be fast and furious, where an error of even 10 seconds could mean the difference between first and fourth placings!
